A green tinted, ultraviolet absorbing glass is disclosed having a standard soda-lime-silica base glass composition and a colorant portion consisting essentially of on a weight basis: less than 2.0% TiO2 and greater than 0.6% total iron (expressed as Fe2O3) with the ratio of FeO/total iron less than

A green tinted, ultraviolet absorbing glass is disclosed having a standard soda-lime-silica base glass composition and a colorant portion consisting essentially of on a weight basis: less than 2.0% TiO2 and greater than 0.6% total iron (expressed as Fe2O3) with the ratio of FeO/total iron less than 0.35. The glass exhibits an ultraviolet transmittance no greater than 38 percent (300 to 400 nanometers) and a luminous transmittance (illuminant A) of at least 70 percent at thicknesses ranging from 0.154 to 0.189 inches.
